It turned out the error I needed to research specifically was ERROR:zygote_host_impl_linux.cc(100). I found a solution here: https://stackoverflow.com/questions/62284578/docker-errorzygote-host-impl-linux-cc89-running-as-root-without-no-sandb And the new Dockerfile is # Use the official Python base image FROM python:3.11-bullseye RUN pip install numpy && pip install setuptools # Copy the debPackages.txt file COPY debPackages.txt . # Install Qt6 dependencies RUN apt-get update && apt-get install $(grep -vE "^\s*#" debPackages.txt | tr "\n" " ") -y # Set the working directory in the container WORKDIR /app # Copy the requirements.txt file COPY requirements.txt . # Upgrade pip RUN pip install --upgrade pip # Install the Python dependencies RUN pip install --no-cache-dir -r requirements.txt # Copy the project files COPY . . ENV PYTHONDONTWRITEBYTECODE=true # Export QT specific settings ENV QT_DEBUG_PLUGINS=1 ENV QT_QPA_PLATFORM=offscreen ENV QTWEBENGINE_DISABLE_SANDBOX=1 RUN pip install . # Expose the port the application runs on EXPOSE 8000 CMD ["coverage", "run", "-m", "pytest"] so adding ENV QTWEBENGINE_DISABLE_SANDBOX=1 fixed everything.

I still haven't found a solution. There is also a ticket in the bugreport system, which hasn't been solved for now, i added my information in order to add more awareness to this issue. I really like the idea of having such a plugin as it makes cross compilation so much easier / cleaner. I really hope that the development will be continued at some point... Here is the link to the ticket: https://bugreports.qt.io/browse/QTCREATORBUG-25981

There are some Docker files in Creator's own repo: https://code.qt.io/cgit/qt-creator/qt-creator.git/tree/tests/manual/docker

Solved using this answer on StackOverflow.

@ZhiCoeus it works！！！i test on ubuntu 16.04 and 20.04 , thanks！！！！

@mviereck Thanks for the command! The syscalls used by my application are the following: access, arch_prctl, brk, close, connect, execve, fstat, futex, getcwd, getdents, geteuid, getpid, getrandom, getuid, lseek, lstat, mmap, mprotect, munmap, openat, prlimit64, read, readlink, rt_sigaction, rt_sigprocmask, set_robust_list, set_tid_address, socket, stat, statx, write From what I can tell, all of these are allowed by the default seccomp profile of Docker 18.06, only the rule for arch_prctl is listed separately. I also verified that Docker has no problems accessing the seccomp file, which could've been a cause for my problem. Perhaps I should do a kernel update, as it currently is my last idea to fix this issue (without using --security-opt seccomp=unconfined).

Hi, AFAIK, no. IIRC KDevelop has some stuff already implemented for Docker, but not Qt Creator.

Hi and welcome to devnet, Why not have Qbs also inside the container ?
